Core Principles

核心原则

Write idiomatic Go code following Go conventions
Utilize Go 1.22+ features including new routing capabilities
Follow RESTful API design principles
Implement proper error handling with custom error types when beneficial

遵循RESTful API设计原则
在合适的场景下使用自定义错误类型实现恰当的错误处理

Code Organization

代码组织

Clean Architecture principles with handlers, services, repositories, and domain models
Interface-driven development with explicit dependency injection
Modular project structure:
- cmd/ - Application entry points
- internal/ - Private application code
- pkg/ - Public libraries
- api/ - API definitions
- configs/ - Configuration files
- test/ - Test files

遵循整洁架构原则，包含处理器、服务、仓库和领域模型
基于接口的开发，实现显式依赖注入
模块化项目结构：
- cmd/ - 应用程序入口
- internal/ - 私有应用代码
- pkg/ - 公共库
- api/ - API定义
- configs/ - 配置文件
- test/ - 测试文件

API Development

API开发

Use the standard library's
```
net/http
```
package
Leverage Go 1.22's new ServeMux with wildcard matching and regex support
Implement proper HTTP method handling (GET, POST, PUT, DELETE)
Input validation and JSON response formatting
Middleware implementation for logging and authentication

使用标准库的
```
net/http
```
包
利用Go 1.22新增的ServeMux，支持通配符匹配和正则表达式
实现恰当的HTTP方法处理（GET、POST、PUT、DELETE）
输入验证和JSON响应格式化
实现用于日志记录和身份验证的中间件

Error Handling

错误处理

Use wrapped errors for traceability
Implement explicit error handling
Return errors rather than panicking
Provide meaningful error messages
Handle errors at appropriate levels

使用包装错误以实现可追溯性
实现显式错误处理
返回错误而非触发panic
提供有意义的错误信息
在合适的层级处理错误

Concurrency

并发

Goroutine safety and context propagation
Use channels for communication between goroutines
Implement proper cancellation with context
Avoid race conditions with proper synchronization

Goroutine安全和上下文传播
使用通道在Goroutine之间进行通信
利用上下文实现恰当的取消操作
通过恰当的同步避免竞态条件

Testing

测试

Table-driven unit testing patterns
Integration testing for APIs
Mocking with interfaces
Use testing package effectively

表驱动单元测试模式
API集成测试
基于接口的Mocking
有效使用testing包

DevOps Integration

DevOps集成

Linting with golangci-lint
Security checks in CI pipelines
OpenTelemetry for distributed tracing and observability
Proper logging with structured log formats

使用golangci-lint进行代码检查
